I finally made the HTML available for download (along with a map of the game), sorry for the long wait! My original plan was to make it available once I had fixed all of the known unintended solutions, but there were a couple I was really struggling with that I just never got around to fixing. I'm still hoping to get through those at some point (I'll update the downloadable version and leave a new reply here when I do) but I wanted to upload this now before I forget again.
Viewing post in I wish we could download the game...
And I'm off and . . . crawling, again. Thanks, Steve. Game hasn't gotten any easier but my lost-progress fears have eased. One, perhaps, tip for Firefox: I unchecked my offline data box in the clear cache box (ctrl+shift+del) and that allows me (so far) to keep my game save. Not sure if this works in other browsers.
